@AterNox @dch82 blocking and reporting work fine.
However, people from corporate social media won't report posts because in their experience, it either doesn't get taken seriously or the admins ignore it. Corporate social media sites don't exactly act on reports in a timely manner.
I'm on my own instance, I moderate for myself. I don't want slurs to exist on my instance at all. However, if I don't see them with my own eyes, I cannot ban the user.
